Copilot Studio vs Cowork: what's the difference?
Cowork is Microsoft's ready-made agent for everyday knowledge work - research, documents, email, reports - used through Copilot and billed by usage. Copilot Studio is the tool for building your own agents: a customer-service bot on your website, an HR assistant trained on your policies, a process that runs against your systems. Studio agents are also metered in Copilot Credits, but building one is a project; using Cowork is a licence and a switch.
For most smaller UK businesses the answer is Cowork first, Studio rarely. Cowork covers the document-and-email layer where the hours actually go, with no build. Studio earns its place when there's a specific, repeated process with its own data - a quoting bot, a first-line support agent - that justifies someone's time to build and maintain it.
The cost shapes differ. Cowork's cost is the people using it: licences plus their usage. A Studio agent's cost is its traffic: every conversation with the bot spends credits, whoever's talking to it, including customers. That can be cheap or startling depending on volume, and it needs its own cap.
They also overlap less than the marketing suggests. Cowork won't build you a customer-facing bot; Studio won't triage your inbox. Pick by the job.
No. Cowork needs a Copilot licence and usage-based billing. Studio is separate.
Both are metered in Copilot Credits through the same usage-based billing, so they draw on the same tenant's credit spend. Give a customer-facing Studio agent its own limit, so its traffic can't eat the budget your team relies on.
The definitions are the easy part. Whether Cowork is the right spend is a different question.
